The webs and topsheets include bicomponent fibers having a first component and a second component, wherein the first component has a different hydrophilicity than the second component. The webs and topsheets include a continuous land area and discrete zones of modified surface energy. One of the first and second components forms an outer surface of the fibers in the continuous land area and the other of the components at least partially forms an outer surface of the fibers in the discrete zones of modified surface energy such that the discrete zones of modified surface energy have a different hydrophilicity than the continuous land area.

An elastic body for cosmetic holding use which can be used for holding a cosmetic such as a foundation, such as a puff that can be used for the application of a cosmetic onto skin, said elastic body being characterized by containing conjugate fibers as constituent fibers, wherein each of the conjugate fibers contains a resin A and a resin B having a higher melting temperature than that of the resin A, and contact parts between the constituent fibers are integrated with the resin A contained in the conjugate fibers; a cosmetic-containing elastic body which comprises the elastic body for cosmetic holding use and a cosmetic contained in the elastic body; and a cosmetic equipped with the cosmetic-containing elastic body.

The present invention addresses the problem of providing: a polishing pad that is long-lasting, has a high polish rate, and is capable of producing a high degree of flatness on polished articles; and a method for manufacturing the polishing pad. The solution provided is to eliminate a sea component from a non-woven fabric that includes a binder fabric and a sea-island type composite fiber composed of the sea component and an island component, the island component having a diameter of 10-2500 nm, and to add a polymer elastic body to the non-woven fabric.
